Harold 1 K. Sylvester, Los Angeles, Ca f. I Application July as, 1938, Serial 110,221,768 Y? v 5 ol ims wwlpzce-iua) My present inventionrelates to theprovision ofhinges andthe operating means therefor, for doors, window sash, shutters or blinds and the like. i

My general objects have been to simplify such structures and thereby permit an economy in the-manufacture thereof and also, .to improve. such structures with reference to dependability,

and functioning. As collateral objects, I desired to produce a structure which will serve for both right and left opening sash etc. without changes and which will be uniformin appearance. That is, I desire to provide a structure in which the control elements j are installed or remaining structure of the hinge.

omitted without-changing the appearance or the As further objects I desired to produce afstrucfture which can be largely made by stamping l operations, and I desired to produce the worm gear or wormwheel by stamping operations so thattheyonly remaining portion of mystructure which requires machining is the worm. a v

I- have obtained the foregoing'objects by means of the structure illustratedin the accompanying drawings, in which my p'resent invention.

.Fig. 3 is a longitudinal section on line 33 of Fig. 2. f a 1 i Fig. 4 is a perspective detail of the cradle for the worm. I l l Fig. 5 is a detail partially in'section, showing the window sash in closed position. v

Fig. 6 is a view similar toFig. 5"s howing' tjhe window sash open 180 degrees in full lines and 90 degrees in dotted lines. u I

Similar reference characters designate similar parts in the respective views.

The structure is largely formed of a suitable gauge or thickness and quality of a 'desiredmaterial, such as iron, mild steel or a stainless, or; rustless metal composition as the customermay desire and be willing to pay for. It was my object to provide a hinge, he leaves or wings whereof constitute a casing within which the operating elements, comprising a worm and a worm-wheel or. wonn-gearfljcould be mounted. In order, to do this the blanks of sheet metal of a proper gauge, are cut soas to provide a central portion H], of a rectangular, longitudinally elongated form, from the longitudinal edges of which extend wings. The wings II are suflicientlywide to provide space which the centralportion lfl and'wing's 11 ex- Shaft and worm housing and ajguide for the for receiving and containing "the worm l2. and its mounting or cradle l3 and a d etachable shaft of a crank M, by means ofjwhi'ch the worm is rotated; and the outer portion of the wings. I l are further extended in-arrear ;1ike form to en: 5 close the worm gear. It willbeunderstood'that the wings are bent at right angleswith the central portion ll! of the blank so as to lie parallel with each other. For greater clearness 'I have M marked theportions of, the wingswhich lie ad- 10 jacentthecentral portiongand constitute, with thegcentral portion, the casing for the worm l2 and its cradle l3"and the shaft of the crank l t, with reference character 15 and the earshaped portion of'the wings l5a.- The two membersof 15" the hingejare ofzthe outline and form above described but one of these members issuificiently ing a wormwheel or worm gear to said outer hinge member.

The edges ofthe wings I I adjacent their inner ends, are extended toprovide rectangular plates 19,. which are bent outwardly from the wings II and are perforated at 2 0 and countersunk at 2| for the passage of screws22j by meansof which they aresecured either to the jamb of the windowcasingor the vertical side rail of thesash or blind. -The inner hinge member is attached tothejainbof the window casi g andthef countersinking is, thereforefori the same'side from 40 tend. The outer hingemember is secured to the side rail 'of the sash or blind andthe countersink'ing. 2| of the plates l9 extending from the outer hinge member are upon the sides opposite the central portion I0 and thewinglportions I l. The inner'end of the central portion, In, of

the inner hinge member, isfextended and bent at right angles, asat 23, andperforated asat 24;?to forma closure for the inner end of the.

shaft of the crankfM. 'l'heQiriner, end of the central portion 10 of theouten'hinge'membei'. isextended and bent at right angles at 23a and the outer edge thereof is slotted,at24a to'register with the perforation 24 in the extension 23 v hinge member.

The mounting or cradle l3 for the worm l2 consists of a strip of metal, the ends whereof are bent to extend parallel with each other in the same direction, as at I to, and the outer edges of the ends l3a" are slotted, as at I3b, to provide journals for the projecting ends iZa of the. hub of the worm 12.

Way I221 to receive the similarly angled end of the shaft or" the crank M. The base of the worm mounting or cradle I3 is secured, in any desired manner, as by spot welding or soldering or braz- I ing, to the inner face of the central portion of the inner hinge forations I The special worm gear which I haveprovided for cooperating with the worm, heretofore described, comprises a pair of .discs 26 which may be cut out and formed by stamping operations. Besides being providedon their peripheral edges with teeth 2? to, cooperate with the worm, they are centrally curved, as at 28, and the central portion of the curved portion is provided with member, Ill, opposite the pera shoulder 29 tocooperate with the perforation E6 to form a journal for the worm-gear.- Within the shoulders 29,,the discs 25 are provided with square perforations 3!! to receive the square shank of the rivet l8 which fixedlysecuresthe wormgear to the outer hinge member. The curved portions 28 of the discs 26 terminate within the peripheries of saiddiscs, at which place 3 l-,--the discs are spotwelded, or otherwise secured together, and the portions of the: discs between the location of the teeth and the place where they are spot welded, or otherwise secured togethen-are spread, as at 32, so that the .teeth in therespective discsstraddle the curvature'of the worm 52. This secures two results. First, the worm is held inits journal slots set, and, Second, by rotating one "disc with'respect t o the other before the discs are secured together, the

desired accuracy of fit between theworm and the worm-gear may be-secured, which fit has heretofore required careful machining in the making of the worm-gear.

It will be seen from the foregoing description,

taken in connection with the drawings, that the inner end of the'inner hingemember is secured to the jamb of the window ordoor frame andthat the rotation of the worm, which ismounted inthe inner hinge member, rotates the worm-gear, which is journaled in the inner hinge member and fixedly secured to the outer hinge member, thereby rotating the inner end of the outer. hinge member which issecuredto the side rail of the door-or sash. .It will be further seen that the turning of a hinge up side down, will render it suitable for either right or-' left swinging doors or sashes; and itwill be also seen that the omission of the worm and worm-- gear from a casing will leave a complete hinge in allrespects similar in action and'appearance door or. sash may be. completely opened; and

The hub of the worm is provided with an angular sectioned passage closed or adjusted in any intermediate position.

It will be particularly noted by reference to Figs. 5 and 6, that the sash or blind is carried from'a closed position within the outer line of the building wall to a completely open position outside of the outer line of the building wall and parallel therewith.

Having described my invention what I claim as new and desire to secure by Letters Patent A hinge, comprising a pair of perforated straps for securing respectively to the jamb of a .window frame and the side rail of a sash,

said straps being formed at their central port-ionsFinto' channels extending laterally there rom, the, parallel flanges of said channels bei extended; said channeled members being proportioned to register and fit together, part for part, a worm journaled in the channel of the-inner of said members and a worm-gear, cooperating with said worm, journaled in the inner of said members and fixedly secured to the outer of said members.

2. A hinge comprising a pair of perforated platesfor securing respectively to the jamb of a window or door frame and the side rail of a sash or 'door, said plates being formed at their central portions into channels extending laterally from said plates, the parallel flanges of saidchannels being further extended to provide ears;at their remote ends, said plates being proportioned to register and one of said channels beingproportionecl to enter the other of said vide" ears, said channels being proportioned one to enter the other; a worm journaled in the inner of said channels and a worm-gear,-co-

operating with nsaiolworm, journaled between thein-ner ofsaid channelsv and fixedly secured to theears of the outer of said channels.

4. A hinge, comprising butt-plates having extendinglaterally therefrom channeled members, one of which is adapted to receive the other, a worm mounted in the inner of said members,

and a wormgear, cooperating with said worm,

journaledbetween the walls oi said inner momber and fixedly secured between the overlaying and underlaying walls of said outer member.

15. A-hinge, comprising butt-plates having extending laterally therefrom channeled members, one of which is adapted to receive the other, awonn, mounted in the inner or said members; and a 'worm gear, cooperating with said worm, journaled between the wallsof said member and fixedly secured between the overlaying and unr y ns walls of said outer member, wormgear comprising a pair'of discs having teeth out upon their respective peripheries, the teeth bearing portions being'spread to straddle thecooperating worm.
